-  Why is that?
  Why is that?  There is difference between functions and expressions:
  programming linguage functions produce values, expressions are values
  which represent symbolic information.  In the past 'max' was ordinary
  value producing function. 'max' used order on expression to pick
  "bigger" argument, quite unlike expected symbolic behaviour.
  Now in FriCAS expressions are no longer ordered and old 'max'
  definition does not work, freeing the name so that we can give
  it symbolic meaning.

[Unevaluated Expressions]?
Expressions like sin(x) appear unevaluated until a value is substituted for x but expressions like max(x,y) return y! Why is that? There is difference between functions and expressions: programming linguage functions produce values, expressions are values which represent symbolic information. In the past max was ordinary value producing function. max used order on expression to pick "bigger" argument, quite unlike expected symbolic behaviour. Now in FriCAS? expressions are no longer ordered and old max definition does not work, freeing the name so that we can give it symbolic meaning.
